2 Claims.

This invention aims to provide novel means for handling water, duringthe settling, chemical treatment and filtration thereof, novel meansbeing supplied for washing out the apparatus upon occasion.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details or construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings:

Fig. 1 shows in top plan, a device constructed in accordance with theinvention;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1;

Fig. 4 is a section on the line 4-4 of Fig. 1;

Fig. 5 is a section on the line 55 of Fig. 4;

Fig. 6 is a section on the line 66 of Fig. 2;

Fig. 7 is a section on the line I--'l of Fig. 1.

In carrying out the invention, there is provided a plurality of circularsettling basins I, supported. on legs 5!. Circular check tanks 2 arelocated in the basins l, at the centers thereof. The check tanks 2 aresupported from the bottoms of the basins I on legs 3. The check tanks 2are much smaller in diameter than the settling basins I and are of lessheight than the settling basins, the tops of the check tanks beingdisposed below the tops of the settling basins.

Lower bearings l are located within the basins l and are secured to theside walls of the basins, near the bottoms of the basins. Upper bearings5 are located within the basins I, above the lower bearings 4 and aresecured to the side walls of the basins. The bearings 4 and 5 may beangle members. The vertical flanges of the upper bearings 5 extendupwardly above the upper edges of the basins I and are provided withkeeper notches 6. The bearings l and 5 of one basin I are disposedclosely adjacent to the bearings of the other basin, the bearings beingdisposed on the extreme inner portions of the basins,

as shown in Figfl, to avoid the use of long connecting conduits betweenthe basins.

Vertical shafts I are mounted to rotate in the bearings 4 and 5. Bames 8are secured intermediate their ends to the lower portions of the shaftsl and are disposed closely adjacent tothe walls of the basins I, as Fig.6 will show. The baiiies 8 are interposed between the lower bearings 4and the bottoms of the basins I, and, therefore, hold the shafts Iagainst upward movement, and for-rotation in the bearings 4 and 5. Attheir upper ends, the shafts I are supplied with angu-.

larly disposed handles 9 which have resiliency enough so that they canbe sprung into and out of the keeper notches 6 in the upper edges of thevertical flanges of the upper bearings 5. I V

A cylindrical, vertical, chemical receiver I9 is disposed between thebasins I and is surmounted by a cap II, which may be removable. The capII has a central bearing I2. An outlet elbow I4 is connected to thebottom of the chemical receiver IO and has an internal bearing I5.

A shaft I6 is journaled for rotation in the bearings I2 and I l. Paddlearms or agitators ll are secured to the shaft I6 and work on the bottomof the receiver I0. An inlet chute I8 is secured to the receiver II],near the upper end thereof, and is provided with a removable closure I9.

A filter 20 is located opposite to the receiver I0 and comprises adrum-like body 2|. A circular tank 22 is disposed within the filter body2! and is of less diameter than the filter body, and is supported on thebottom of the body. The tank 22 is of less height than the body 2|.Parallel outlet tubes 23 are located on the bottom of the tank 22 andare perforated to receive water. A quantity of sand 24, or otherfiltering material, is disposed in the tank 22, on top of the outlettubes 23.

Water under pressure enters the chemical receiver III by way of atangential pipe 25 located near the bottom of the receiver and istreated, for any desired purpose, by suitable material (not shown) inthe receiver. The treated water, proceeding through the pipe 25, strikesthe paddles I1 and causes them to rotate, along with the shaft I6. Inthis way, a thorough agitation of the contents of the receiver II] isobtained. The flow of water through the pipe 25 is governed by a handvalve 26 in the pipe. The treated water leaves the receiver II] by wayof a pipe 2?, disposed about opposite to the inlet pipe 25. The pipe 21has a transverse head 28. Hand valves 29 are interposed in the pipe 28,on opposite sides of the pipe 21. The pipe 21 opens into the settlingbasins I, midway of the length of the baliles 8, as shown in Figs. 6 and3.

The water, entering the settling basins I, by way of the head 28,circulates or swirls in the basins, the speed of circulation beingregulated by the valves 29. Water carrying a small amount of heavysuspended matter can be run through faster than water which carries alarger amount of lighter suspended matter. The water rises in the basinsand overflows into the check tanks 2, which segregate the water after ithas been subjected to the settling process. The check tanks 2 are sodesignated, because they prevent the water from moving directly from thesettling by way of the pipes 30, rises, as shown in Fig. 7,

until it overflows into the tank 22, where material not removed in thebasin is caught by the sand or other filtering material 24, the waterentering the outlet tubes 23. From the tubes 23, water leaves by a pipe34, connected to the tubes 23, the flow through the pipe 34 being underthe governance of a hand valve 3|. The water passes from the pipe 34into a clear water receptacle 32, u

the last of the suspended matter having been removed in the filter 20.

In the event that it is desired to flush out the filter 20, that can bedone by closing the valve 3| in the pipe 34 and opening a valve 33 in apipe 35, branched all from the pipe 34. Water flows through the pipe 35and through the tubes 23, which then become nozzle tubes, the waterpassing upwardly through the filtering material 24 and overflowing intothe body 2| of the filter n 20. The washing water leaves the body 2| byway of a lateral pipe 36, located near the bottom of the body 2|, a handvalve 31 being interposed in the pipe 36.

A pipe 38 is extended inwardly between the :1-

basins I and is provided at its inner end with a transverse head 39,opening into the basins the pipe being connected to the tubes 23. Handvalves 4|] are located in the head 39, on opposite sides of theextension 38 of the pipe 34.

Water enters the basins by way of the pipe 33 and the head 39, andefiects a thorough cleaning of the basins, the washing water leaving theAt their outer ends, the pipes 3!),

basins by way of pipes 4|, opening through the bottoms of the basins,below the check tank 2. The fiow through the pipes 4| is regulated orstopped by hand valves 42, interposed in the said pipes, and locatedoutwardly of the basins The operation of the device has been set forthhereinbefore, in connection with the piping or conduits, and need not berepeated at this place. The machine is so constructed that a supply ofclear water is available readily, the water being treated chemically.The baflles 8 of Figs. 6 and 3 are important elements, in that theyregulate the circulating motion of the water in the basins a thoroughprecipitation of heavier suspended foreign matter in the water beingbrought about. If the water does not contain much suspended matter, thewater may be permitted to travel by a short path from the pipe 28 to thecheck tank 2, the angle between the baffle 8 and the axis of the pipebeing increased. As the angle is reduced, toward a little more than 90degrees, the flow is caused to follow around the basin-I, the waterfollows a longer path, and there is more time for precipitation of thesuspended matter.

What is claimed is:

1. In a water-treating apparatus, a settling basin having an outlet, achemical receiver, a conduit leading from the receiver to the basin, anagitator mounted to rotate about a vertical axis, in direct contact withthe bottom of the receiver, and a water inlet for the receiver, theinlet discharging directly upon the agitator to secure rotation thereof,the receiver having a central outlet in its bottom, the agitator beingopen for the passage of water therethrough, and to the outlet of thereceiver.

2. In a water-treating apparatus, a settling basin having an outlet, achemical receiver, an elbow secured to the central portion of the bottomof the receiver and having an internal bearing, an outlet conduitconnected to the elbow and discharging into the basin, a lid removablymounted on the receiver, a shaft journaled in the lid and having itslower end removably stepped for rotation in the bearing, an agitatorcarried by the shaft and movable in direct contact with the bottom ofthe receiver, the agitator being open for the passage of liquidtherethrough, and to the elbow, and a side water inlet for the receiver,the inlet discharging directly against the agitator, to secure rotationthereof.
